Answer:

Osmosis

Explanation:

In a highly concentrated salt solution, concentration of water is comparatively lower than the fluid inside red blood cells. This develops a concentration gradient.

Due to this difference in concentration, the water starts flowing out of the red blood cells across its permeable layer. Due to this movement of water, red blood cell shrinks. This physical phenomenon in which a substance move from a region of high concentration to a region with lower concentration across any permeable membrane is called Osmosis.

This process is called osmosis whereby water exits the cell through its selectively permeable membrane and into the salt solution to dilute and balance the pressure caused by the concentrated salt solution.

Match each leukocyte to its normal percentage in a differential cell count. A. 50-70% B. 20-40% C. 2-8% D. 1-4% E. < 1% basop

Vsevolod [243]

Answers:

A. 50-70% - neutrophils

B. 20-40% - Lymphocytes

C. 2-8% - monocytes

D. 1-4% - eosinophils

E. < 1% - basophils

Explanation:

The blood differential test is used to estimate the percentage of each class of white blood cell (WBC) present in the blood and to indicate the presence of abnormal or immature cells.

The Test is Performed by taking of blood sample which is smeared onto a glass slide, then it's stained with a unique dye to indicate the class of white blood cells.

The Five class of white blood cells are

Neutrophils

Lymphocytes (B cells and T cells)

Monocytes

Eosinophils

Basophils

The different class of white blood cells are given as a percentage:

Neutrophils: 40% to 60%

Lymphocytes: 20% to 40%

Monocytes: 2% to 8%

Eosinophils: 1% to 4%

Basophils: 0.5% to 1%

Band (young neutrophil): 0% to 3%
